QMX3.P74-1BSC Room Operator Unit KNX with Sensors for Temperature Humidity CO2 Segmented Backlit Display Touchkeys Black S55624-H127

The QMX3.P74-1BSC is the black-finish variant of the QMX3 triple-sensor room operator, designed to measure temperature, relative humidity, and CO2 concentration via KNX protocol. The CO2 sensor covers a range of 400 to 10,000 ppm, enabling demand-controlled ventilation integrated through the KNX backbone.

Temperature control utilizes PWM or PID modulating algorithms for pure heating, pure cooling, or combined HVAC modes. Three independently configured thresholds trigger fan speed changes and valve positioning signals for comprehensive indoor air quality automation in any occupied zone. Setpoints can be adjusted via KNX bus commands or the touchkey panel interface.

• Luxury hotels and boutique offices choose the QMX3.P74-1BSC where a black panel matches interior schemes while delivering full CO2, temperature, and humidity sensing capabilities
• Smart apartment buildings utilize it in living rooms to automate ventilation based on occupancy CO2 levels
• Three-parameter data feed supports LEED, WELL, and ESG compliance reporting requirements
• Drop-in replacement for the white P74 variant in projects requiring a dark-panel aesthetic
